1 November-2023 climate summary

  • November-2023 was on average 3.75°C more warmer than normal.
  • November-2023 was drier then normal for lower latitude regions while wetter then normal at north-west region.
  • The average of previous 12 months climate parameters indicate that BC experienced substantially warmer and slightly drier climate then normal between October 2022 and November 2023.
  • The mean November 2023temperature in BC is increasing but the rate of increase is not statistically.
  • The long-term November 2023 precipitation indicate slight increase (0.23 mm per year) in spatially averaged total precipitation across BC .

Below you find the spatial anomalies and long term trend of air temperature, vapor pressure deficit (VPD), total monthly precipitation, relative humidity (RH), and volumetric soil moisture (0 - 1m depth) for the month of November-2023.
